A kind of soft pack cell attachment structure of cylinder manifold and the application cylinder manifold
Technical field
What the utility model was related to soft pack cell is connected in series technical field, and in particular to a kind of cylinder manifold and apply the remittance
Flow the soft pack cell attachment structure of plate.
Background technology
At present, using polymer as the energy source device of carrier, such as portable power source, electrical source of power, energy storage device are more using poly-
Compound battery core, i.e. soft pack cell.Soft pack cell have it is light, thin, have extended cycle life, have a safety feature, energy density is high, electric discharge flat
The many advantages such as platform is stable, power-performance is outstanding, environment friendly and pollution-free, thus it is able to fast development.
It is difficult the electricity for meeting some high voltage operations in use but the voltage of single soft pack cell battery core is relatively low
The use requirement of subclass equipment, therefore generally require to connect two or more soft pack cell and/or used in parallel.
But, it is single battery core " weakness " because the lug of soft pack cell is softer and stress is easily broken, the lug of single battery core is usually
With laser welding on the positive and negative electrode inside battery core, so lug is unable to stress, can not pull, can not shake, otherwise easily make
Come off into solder joint.It is general to carry out direct scolding tin processing using to soft pack cell during the connection in series-parallel connection of existing soft pack cell
Mode, directly welds wire, then two battery cores is connected by wire on cell polar ear.But it is due to that battery core body is thermo-labile,
On its lug during welding lead, scolding tin can make battery core connection sheet localized hyperthermia, easily cause unrepairable to battery core inside
Infringement, makes battery core occur leakage in follow-up use, acts the phenomenon such as rise, the overall performance of influence energy source device and life-span, even
There is potential safety hazard.
, can either in view of the above problems, it is necessary to propose a kind of connected mode for being directed to two and two or more soft pack cell
The high voltage of energy source device, long continuation of the journey use requirement are met, again can be to the side such as attachment structure and manufacture craft of soft pack cell
Face makes moderate progress.
